I replaced the main PCB
I did not change the spark/sense board or the electrode as I would have thought a fault with either of these would cause a lockout.
To be honest I have just found out that Vokera are offering a repair service for £169 inclucing call out, parts & labour...
Cheers Tony
I too wondered what could be common to both.......
Secondary ( DHW ) thermistor .............. Tried a new one
PCB.............. Tried a new one.
Got me baffled this one :?: :?: :?:
Hi I have a Vokera compact 28 boiler. It has developed a fult when heat is being called for the boiler ignites OK but after a few seconds .... longer sometimes it turns off again, NOT LOCKOUT. then fires up again runs, stops and this continues while heat is being called for. The fault happens...
